Samsung is to unveil a new super-high resolution panel which could set the standard for notebook displays. This week, the company will launch a 13.3-inch QHD 3200 x 1800 panel with 276 pixels-per-inch (PPI), and offers greater pixel densities than Apple's Retina MacBook Pro 13 (239 PPI) and Google's Chromebook Pixel (227 PPI). Samsung has yet to confirm if its LCD panel will come to new ultrabooks, but if it does, Toshiba's 13.3-inch Kirabook — with its impressive 2560 x 1440 display — could have some high-resolution competition in the near future.
